generic nomenclature. Zetterstedt has adopted (1) Hirtea Fb. (1798) for 

 Bibio Geoffroy (1764) ; Hirtea Scopoli (1763) being a different genus. 

 (2) Chenesia Macq. (1834) for Orphnephila Haliday(1831), or Thaumalea 

 Ruthe (same year). (3) Sicus Fb. (1798) for Coenomyia Latr. (1797) ; 

 Sicus of Scopoli (1763) being Myopa. (4) Eristalis FaUen (1810) for 

 Chilosia Mg. ; whereas Eristalis was first named and characterized by 

 Latreille in 1804, while Eristalis of Fb. Antl. (1805) is made up of 

 species of the genera Chilosia, Eristalis, Helophilus, Merodon, Mallota, 

 Milesia, Eumerns, Pipiza and Chrysogaster. (5) Syrphus Fallen, for Eris- 

 talis Latr.; Meigen having defined the genus Syrphus otherwise in 1803, 

 and Syrphus of Fb. Antl. including Volucella and Sericomyia along with 

 part of Eristalis. (6) Scaeva Fb. (1805) for Syrphus, previously applied 

 by Meigen as above. (7) Scatomyza Fallen (1810) for Scatophaga Mg. 

 (1803) and (8) Scatophaga Fallen for Psila Mg. (1803), being tour years 

 before Jurine applied the name of Psilus to the Hymenopterous genus 

 Diapria Latr. (1797). (9) Oxyrhina Mg. (1838) for Trigonometopus 

 Macq. (1835). (lO)UlidiaMg. (1826) for Mosillus Latr. (1804), or Chry- 

 somyza Fallen (1817). But Ulidia also maybe retained, being limited, 

 according to Loew's suggestion (Beytr. i. 27), to U. erythrophthalma and 

 the allied species. 



Here we close the chapter of criticism ; and if we should seem to have 

 discharged the task in a spirit more captious than tolerant, the volumes on 

 which we have dwelt so long do not need, and could not gain by, any com- 

 mendation we might bestow, while every correction, and every doubt, may 

 contribute in some small degree to their better use, which we would desire 

 to see more general in the hands of our fellow-students. We lay them 

 down, glad to see that the latest portions of his long labours betray no 

 symptoms of failing eyes or energy diminished, and hoping that the vene- 

 rable author, now in his seventieth year, may be enabled, next, to complete 

 a like history of the HEMIPTERA of Sweden, which we are authorized to 

 expect from his hand. A. H. H.
